(KGTV) - Homeland Security Secretary Kirstjen Nielsen was in San Diego Tuesday morning to tour the border wall prototypes, according to ABC News.

ABC News reported Nielsen was in town to get a first-hand look at the eight prototypes in the Otay Mesa area that were built by private contractors, but further details on her trip were not immediately available.

After her exit, county workers posted several notices prohibiting potentially dangerous objects and any “implement of a riot” at the road that leads into the border wall prototype site from January 5 to January 10.

"We want to be able to see through ... we have a lot of help from the Border Patrol and from the ICE agents," Trump said. "We're getting their input on the wall, because who knows better than them."

No timetable was given for when Trump could head to San Diego to see the prototypes. In the past, the White House has not commented on if and when the president could visit the site.

U.S. Customs and Border Protection officials have been administering a series of test to each of the eight, 30-foot high prototypes near Otay Mesa. Tests include measuring how easy or difficult it is to climb or scale the walls and if people can tunnel underneath or break through them.

Aesthetics are also a part of the inspections.

The prototypes were completed in October after construction began in September. Officials have been given 60 days since completion to evaluate them.
